REVERSlNG-GEARING FOR WASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 400,246, dated March 26, 1889.

Application filed February 10, 1887. Serial No. 227,201. (No model.)

To all whom may concern.-

Be it known that 1, JOHN M. OAKLEY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Reversing-Gearing for VVashing-Machines and for other Purposes, of which the followin g is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification. a

My invention relates to improvements in that class of gearing to be applied to washing-machines in which a stationary shell and an inner revolving cylinder are used, whereby the inside cylinder is made to revolve in,

opposite directions automatically and alternately, as will be more fully described hereinafter.

The object of myinvention is to produce a cheap, simple, and durable device, whereby the inside cylinder of a washing-machine or an agitating-machine is made to revolve in opposite directions automatically and alternately or continuously, and with suitable gears and levers starting, stopping, and locking devices and one that can be operated by unskilled labor.

Figure 1 is a side view or elevation of the reversing mechanism, also an end section of the inside and outside cylinders with shaft and gear-wheel. Fig. 2 is an end elevation of the iron frame. Fig. 3 is a view of the top Fig. A is a detail elevation and partial section of the reciprocating bar I and some of its connections. Fig. 5 is a detail plan view, on a reduced scale, showing the connections between the cylindershaft and the pulleyshaft.

A, Fig. 1, represents a section of the outer casing or tank, in which is contained the revolving or inside cylinder, B, both being constructed of wood or other suit-able material. The shaft C, to which the cylinder B is attached, is shown back of and at one side of the shaft F. The cylinder-shaft and easing are of any usual and well-known constructions and need not be specially described. A 1 gear-wheel, O, is firmly keyed to the journalshaft 0, Fig. 1, and meshes with a pinion, D,

keyed to the pulley-shaft F, by which means the cylinder B is caused to revolve, as more fully described hereinafter.

E is an iron frame made of one or more pieces of metal with journal and bolt holes through it, and with means to attach it firmly to the end of the casingA, and of sufficient strength to support the pulley-shaft and other gearing, as shown in Figs. 1 and 2.

F is the pulley-shaft, which is journaled into and revolves in the frame E. At or near one end of this shaft and within the frame is the pinion D, firmly keyed to it. At the opposite end is a worm or screw, D. This worm is made on the shaft F, the object of which is described hereinafter. Near the center of the shaft F are the pulley or belt wheels G, G, and G The pulley-wheel G has less face surface than the pulley-wheels G and G and it is firmly keyed to the shaft F. On opposite sides of the pulley G are the two idlers or loose pulleys G and G which turn freely on the shaft.

H is a wheel meshing into and operated by the screw or worm D on the shaft F. This wheel revolves on a short shaft, 11, running at right angles to the shaft F, and is supported in the frame E, as shown in Figs. 1 and 2. On one side of the wheel H, between the hub and the outer edge, is a pin or projection extending out one inch, more or less, as shown at H Figs. 1 and 4, the object being described hereinafter.

I is a flat metal lever or bar operated by the pin or projection on the wheel H. This lever or bar is enlarged at one end, and has a slotted or oblong opening through it, as shown at 1, Figs. 1 and 4. At or near the opposite end it has two small slot-ted openings,

as shown in Fig. 4- The object of the slotted opening in the large end is to allow it to pass over the short shaft H, holding and guiding it between the wheel II and frame E. The object of the two small slotted openings is to attach and adjust two pieces of metal, 1 and 1, by means of belts or rivets, to the bar I, to

regulate its length of stroke and motion. These pieces extend a short distance below the bar, and are separated from each other one inch, more or less, as shown in Fig. at. On one side of thebar 1, at the enlarged end, are

two projeetions extending out from, the side of the bar one ilN'll, more or less, one beingabove the slotted opening and the other below it and near opposite ends of the slotted opening, as shown at l and I, Fig. at.

.T is an operating-lever connected at the lower end by a movable joint; to the frame E near the hub or hearing of the main shaft F, as shown at .l, 'I ig. I. This lover extends up to and above the top ol the frame .IC and Ioelcs into the belt-shitting bar, described hereinafter. Near the center of the lever .I a pin projects out one ineh, more or less, as shown at .I, Figs. 1 and 4.

K 's a weighted lever, pivoted in the hearing It, and having a ball or weight on the top, and with two arms, ii and ii, rising upward and outward. The outward end. of one arm has a lag, or stop, Ii. The object is to look the lmltshit'ting bar by pressing the in; IQ

into a slot in the top of the heItshiI'ting bar, as shown at Ii, Figs. '1 and I At the outer end of the otherarm is a pin. To this pin on arm it" a link, I), having a slotted opening near the top, is eonmreted. Said lever is eonneeted at the bottom by a movable joint to the bar I, as shown at 1?, Figs. l and 4;. The weighted lever it is plaeed between two evepieees east on the topot' the frame It, as shown at Ii, Figs. 1 and Ii, and held in position by any suitable means. The top of the frame I is made flat, and it has two guides, I. .I.,above the top. (In the top of the flat part; of the frame is a movinglnngll, held in plaee by the guides I. I), under which said bar )1 moves when eonneetial to the lever .l, as lnn'efnaliter deseribed. ()n the top of the moving bar M are two e i'e-pieees, in. and w, at a suitable distanee apart. 'Ihroue'h eaeh of these e ve pieces is passed a bar or rod having a beltshipper, N and N, which engage the beltsin the ordinary wav These bars or rods are ad justed by a set-serew, in m", in the top of the eve-piece. At one side of the moving bar Til, near one end, is a recess, I, into which the lever .I loelcs. (In the upper side of the mow in bar .il, near one end, is a rising head or projection, l, with a groove, ii, aeross it, into whieh the right-angled pieoe on the weighted lever It drops when the lever is thrown back toward the machine, thus stopping and locking the maehine, said groove K being shown in Irigs. l and 33.

All the various parts of the gearing and levers herein deseribed are made of iron orsteel or other suitable material.

R and R, as shown. by the dotted lines in Fig. 1, which belts are driven by appropriate shatting and pulleys in such a manner that the belt R travels in the direction indicated by the arrow on its surface, and the belt R travels in an opposite direction, as indicated by its arrow. Should both of these belts be driven by the sameshalt, one oI' them mustbeerossed in order to obtain this opposite motion. The belts are caused to remain on the idlers or loose pulleys Zx and at by being passed. through the oval or U-shaped rin N and N, connected to the moving bar M, said bar being held in, position by the guides L I, on the top of theframeE, nnt'lerwhieh it-moves. To start the maehin ihebeltshaving been properly adjusted, the weighted lever K is thrown forward, thus releasing the moving bar M and allowing the lever or bar I to drop down on the pin or pro jeetion J near the center ol' the operating-lover .I, this pin acting between the adjnsting-pieees I and I. The wheel Il isrevolved by the worm or screw, the pin or pro- ,ji etion II) on the side of the wheel. II acting against the pins or projections I" and I on the side of the lover or bar I. A back and forward motion is given to the bar I every revolution of the wheel II. This motion is imlmrted to the moving bar ill by the operatinglever .I, thus shifting the belts on the pulleys and giving the requisite reversing motion to the inside cylinder.

rllaving'it'ullv desta'ibed my invention, what I desire to claim and seei'lro by Letters Patent is I. The lever or bar I, having slotted openings therein, and projections, as I l, and adjusting-pieces I l thereon, in eornbination with the operating-lev r .T, belt-shifting bar M, and frame I substantially as (TOSOl'lbGtl.
